Hi,
I am using dbus interface + wpa_supplicant 2.5. My WiFi interface is
working fine. With p2p interface I am facing problems. I invoke my
wpa_supplicant as
wpa_supplicant -iwlan0 -u -B -c/etc/wpa_supplicant.conf
I send the below command to query the available interfaces
dbus-send --system --print-reply --dest=fi.w1.wpa_supplicant1
/fi/w1/wpa_supplicant1 org.freedesktop.DBus.Properties.Get
string:fi.w1.wpa_supplicant1 string:Interfaces
But with this my wpa_supplicant gets killed.
With wpa_supplicant 2.1, I get the dbus-send command successfully return
dbus-send --system --print-reply --dest=fi.w1.wpa_supplicant1
/fi/w1/wpa_supplicant1 org.freedesktop.DBus.Properties.Get
string:fi.w1.wpa_supplicant1 string:Interfaces
method return sender=:1.5 -> dest=:1.11 reply_serial=2
variant array [
object path "/fi/w1/wpa_supplicant1/Interfaces/3"
object path "/fi/w1/wpa_supplicant1/Interfaces/1"
]
With wpa_supplicant 2.1 the interface for p2p is p2p0. With wpa 2.5,
the p2p-dev-wlan0 is created internally. But the GetInterface API
fails when p2p-dev-wlan0 is given as parameter for GetInterface. All
the p2p_group_add fails either. I am not sure if I am missing any
configuration?
Attached my wpa_supplicant debug log.
Regards,
Johncy.
